As you all know, we still lack some battle sprites for the blue and green minerals (moonstone and valestone respectively), so here is where I'm going to suggest my ideas on what those two should be.

1.
The green one, should be some kind of airborne animal. Since we haven't got one of those yet, maybe a bird or a butterfly. It can have a special reskin as a snipe or something too.

Drakons focus on dealing damage, Seraphynxes on reducing it, and Maskeraiths on debilitating enemies in general.

The green sprite will focus something else, something I feel is very important here in SK.

Put it like 2 in CSK at elevator to prevent
Phantom when you are waiting for gate change...

"When I was but a squirt, a midst a boring school cirriculum and a personal hit list as an antic rogue lied only Grampa Leif's stories as relief from all the pandemonium, yes a place where I could live--a place where I could dream.As I walk past the looted corpses with my blood-stained blade today,I often think back to his tales--an experience to which were ours and ours alone.

People sometimes complain about how they miss an event for whatever reason and therefore missed out on its rewards (costumes and gear usually). What if there was a way to get some of the event experiance when the event is past?

First of all, the Monster Encounter Tracker, it tracks the monsters you've encountered and killed (Because "Monster Defeat Counter" doesn't sound right...). There would be 7 types: Beast, Fiend, Undead, Construct, Gremlin, Slime and Unknown, all are acquired from (Most) Prizeboxes and Lockboxes. Let's say for the sake of this argument, the Heart of Ice (Maulos' Maul) is a weapon you can acquire as a rare drop from Maulos. For your bragging rights, perhaps you want to say "I only had to fight Maulos 20 times to get it!", or something like that. This lets you do that, with proof.

So, after a while of playing through Spiral Knights, I found that the arcade is a little more... stale, than the story missions. The story missions have special arenas, rooms, and other qualities that make them different than say, an arena level. In shocking sentient sentinels, you have to fight (spoilers) Sputterspark's Sparkcaster. Why not have a scenario arena with the Sparkcaster? I just think that the arcade gets stale the longer you play. Throwing in these rooms could get players more invested in Spiral Knights, and thus, having them play more, and pay more.

WARNING: HUGE BLOCKS OF TEXT AHEAD. Skip down to my comment for a TL;DR summary of this part. This idea is in a few parts:

HOMECOMING PART I: Social Changes
HOMECOMING PART II: Shuttle
HOMECOMING PART III: Ready Room Renovation
HOMECOMING PART IV: Guild Lab
HOMECOMING PART V: Guild Stash

Must be fixxed.

What about giving the bombers a new bomb right now? We are the only ones who got nothing this year besides a mediocre piece of shadow armor that is not worth crafting since it requires the same rare materials as the Black Kat set, which is a lot better than Kat Hiss. What to give us? What about an elemental or a shadow version of the Dark Briar Barrage? It is one of the most useful bombs and it doesn't blind party members as much as Nitronome does.

I've been playing Spiral Knights off and on for about two years. It used to be something great, and even the grinding didn't bother me that much.
But then came a time when those levels kinda lost their charm, you know? I felt the pain of the grind a bit more. Once you run through the same levels over and over, the challenge fades. Eventually, OOO decided to release some new levels. The problem?

THEY WERE EVENTS. A new part of the game, only accessible at certain points of the year.
I could see it with the Winterfest levels, as they're holiday themed.
